Digital Quadrature Tuner
The Digital Quadrature Tuner (DQT) provides many of the
functions required for digital demodulation. These functions
include carrier LO generation and mixing, baseband
sampling, programmable bandwidth filtering, baseband AGC,
and IF AGC error detection. Serial control inputs are provided
which can be used to interface with external symbol and
carrier tracking loops. These elements make the DQT ideal
for demodulator applications with multiple operational modes
or data rates. The DQT may be used with HSP50210 Digital
Costas Loop to function as a demodulator for BPSK, QPSK,
8-PSK OQPSK, FSK, FM, and AM signals.
The DQT processes a real or complex input digitized at rates
up to 52 MSPS. The channel of interest is shifted to DC by a
complex multiplication with the internal LO. The quadrature
LO is generated by a numerically controlled oscillator (NCO)
with a tuning resolution of 0.012Hz at a 52MHz sample rate.
The output of the complex multiplier is gain corrected and fed
into identical low pass FIR filters. Each filter is comprised of a
decimating low pass filter followed by an optional
compensation filter. The decimating low pass filter is a 3
stage Cascaded-Integrator-Comb (CIC) filter. The CIC filter
can be configured as an integrate and dump filter or a third
order CIC filter with a (sin(X)/X)
3
response. Compensation
filters are provided to flatten the (sin(X)/X)
N
response of the
CIC. If none of the filtering options are desired, they may be
bypassed. The filter bandwidth is set by the decimation rate of
the CIC filter. The decimation rate may be fixed or adjusted
dynamically by a symbol tracking loop to synchronize the
output samples to symbol boundaries. The decimation rate
may range from 1-4096. An internal AGC loop is provided to
maintain the output magnitude at a desired level. Also, an
input level detector can be used to supply error signal for an
external IF AGC loop closed around the A/D.
The DQT output is provided in either serial or parallel formats
to support interfacing with a variety DSP processors or digital
filter components. This device is configurable over a general
purpose 8-bit parallel bidirectional microprocessor control bus.
